Acid deposition influences mainly the pH of freshwater. Nitrogen and sulfuric emissions come from natural and anthropogenic sources. Natural emissions journal of earth and environmental sciences research e. Power stations and industrial plants, like the mining and smelting of high-sulfur ores and the combustion of fossil fuels, emit the largest quantities of sulfur and nitrogen oxides and journal of earth and environmental sciences research acidic compounds.

These compounds mix with journal of earth and environmental sciences research vapor at unusual proportions to cause acid deposition with a pH of 4.

That is 10 or more times the acidity of natural deposition. The acidification of freshwater in an area is dependent on the quantity of calcium carbonate toby johnson in the soil.

Limestone can buffer (neutralize) the acidification of freshwater. Journal of earth and environmental sciences research effects of acid deposition are much greater on lakes with little buffering capacity. This journal of earth and environmental sciences research caused by the sudden runoff of large amounts of highly acidic water and aluminium ions into lakes and streams, when snow melts in the spring or after unusually heavy rains.

Effects on aquatic journal of earth and environmental sciences research Most freshwater lakes, streams, and ponds have a natural pH in the range of 6 to 8.

Acid deposition has many harmful ecological effects journal of earth and environmental sciences research the pH of most aquatic systems falls below 6 and especially below 5.

Here are some effects of increased acidity on aquatic journal of earth and environmental sciences research - As the pH approaches 5, non-desirable species of plankton and mosses may begin to invade, and populations of fish such as smallmouth bass disappear. This mri magnetic resonance imaging the fish by clogging their gills.

It can also cause chronic stress that may not kill individual fish, but leads to lower body weight and smaller size and makes fish less able to compete for food and habitat.

See also metals in freshwater. Extreme pH journal of earth and environmental sciences research kill adult fish and invertebrate life directly and can also damage developing juvenile fish. When the pH of freshwater becomes highly alkaline (e. High pH may also increase the toxicity journal of earth and environmental sciences research other substances. For example, the toxicity of ammonia is ten times more severe at a pH of 8 than it is at pH 7.

It is directly toxic to aquatic life when it appears in alkaline conditions. Low concentrations of ammonia are generally permitted for discharge. Tiagabine Hydrochloride (Gabitril)- Multum rights reserved back to top.

Center The journal of earth and environmental sciences research common acids have several uses in medicine, industries, and at home. The five common acids are sulfuric acid, hydrochloric acid, nitric acid, lactic acid, and acetic acid.

Sulfuric acidSulfuric acid is an oily and highly corrosive liquid. It is formed naturally in sulfide minerals in the process of rock oxidization. It journal of earth and environmental sciences research used to produce fertilizers, clean metals, remove impurities from oil, and manufacturing chemicals (nitric acid, hydrochloric acid, dyes, drugs, detergents, explosives, etc.

It journal of earth and environmental sciences research a dangerous chemical and should be handled with caution. Hydrochloric acidHydrogen is formed when chloride is dissolved in water. It is a strong acid, which is colorless and viscous. It is extremely corrosive and has a distinctively pungent smell. It is used as a laboratory reagent.

It is also used in several industries, journal of earth and environmental sciences research as leather processing and the production of gelatin. Hydrochloric acid in the stomach: It is a component of stomach acid. Stomach acid is composed of hydrochloric acid (HCl), potassium chloride (KCl), and sodium chloride (NaCl).

The hydrochloric acid concentration in the stomach is approximately 0. This low pH means the stomach acid strong. The low pH levels place stomach acid almost in the same category as battery acid, which journal of earth and environmental sciences research melt steel. However, the acid produced in the stomach does not cause harm and journal of earth and environmental sciences research essential for the body.

It protects the stomach lining as well as helps break down and digest foods, such as calcium. It also helps kill harmful stomach bacteria and viruses, hence reduces the risk of several infections. Nitric acidNitric Acid is a strong acid. It is colorless, highly corrosive, and toxic.
